1990 2.9 map sensor?

[1986RangerXL]

Thanks, I just triple checked and there's no MAP on the firewall or on the fender. I do have a MAF right after the airbox so, mystery solved.

Interesting. Can you post a pic?

Sure, here goes, the MAF sensor (I previously replaced it), the location where normally speaking the MAP sensor would be on the firewall, and a pic of the other side of the engine for good measure:

They sure did change things around from year to year. I have a 1986 ranger with a 2.9 and it's MAP sensor is mounted on the pass side fender among st all that other junk over there.

Can you also get a photo of the tags on your ecm? This was a nightmare when I tried to do the maf conversion. If I have the box and strategy codes, I can get the binaries.

Oh cool. I wasn't sure they had a MAF 2.9, but that looks like MAF to me

Yup. My '86 has it on the fender, but my '87 body does have the bracket on firewall

They were 90-92 (IIRC) and cali only.

THANK YOU

Sure thing. Actually, after posting the pic, I decided to get a used ECU with the same part no. off Ebay, something I had been meaning to do for a while. It was only $65 and has a 60 day return guarantee so, as soon as it arrives, I can make sure it works and have it on hand as a spare.

Did they have more pcms? I have a pile of new in box Ford/Motorcraft 2.9 MAF sensors and housings here.

PJ412,
Since I’m getting my 89 back on the road after the previous owner let it sit a few years, should I disconnect the battery and change the MAF and IAC as a preventive measure?

I fire through parts too fast to answer that one... Experiments means frequent changes.

Agreed. Thanks.
